PoweredUSB

PoweredUSB, also known as Retail USB, USB PlusPower, and USB +Power, is an addition to the Universal Serial Bus standard that allows for higher-power devices to obtain power through their USB host instead of requiring an independent power supply or external AC adapter. It is mostly used in point-of-sale equipment, such as receipt printers and barcode readers.

History

PoweredUSB, as a proprietary variant of USB, was developed and proposed by IBM, Berg (now FCI), NCR and Microsoft between 1998 and 1999, with the last revision (0.8g) issued in 2004. The specification is not endorsed by the USB Implementers Forum (USB-IF). IBM, who owns patents to PoweredUSB, charges a licensing fee for its use.

PoweredUSB was licensed by Hewlett-Packard, Cyberdata, Fujitsu, Wincor and others.

Implementation

PoweredUSB uses a more complex connector than standard USB, maintaining the standard USB 1.x/2.0 interface for data communications and adding a second connector for power. Physically, it is essentially two connectors stacked such that the bottom connector accepts a standard USB plug and the top connector takes a power plug.

Hydroelectric power in Himachal Pradesh

Himachal Pradesh is extremely rich in its hydroelectricity resources. The state is having about twenty five percent of the national potential in this aspect. It has been estimated that about 27,436 MW of hydel power can be generated in the state by the construction of various hydel projects on the five perennial river basins no matter they are major, medium or small. Out of total hydel potential of the state, 3934.74MW is harnessed so far, out of which only 7.6% is under the control of Himachal Pradesh Government while the rest being exploited by the Central Government. The state government has been giving the highest priority for its development, since hydel generation can meet the growing need of power for industry, agriculture and rural electrification. It is also the biggest source of income to the state as it provides electricity to the other states also.

Himachal has enough resources to generate surplus power but, sometimes this is a misconception as in winters the power shortage overshoots ten lakh units per day due to less flow of water in rivers and at the same time increase in lighting and heating load. Due to increased industrialization and rural electrification this figure is expected to rise even further.

Power (Fast novel)

Power is a 1962 novel by Howard Fast detailing the rise of the fictional Benjamin Holt, leader of the International Miner's Union, in the 1920s and 1930s.

Written from the perspective of a journalist – Alvin Cutter – it follows Ben Holt's life from a number of different perspectives, from meeting his wife to becoming a leading light in the industrial trade union movement.

Solar (Taeyang album)

Solar is the first full-length solo album by Korean singer Taeyang, member of Big Bang. The album was released in two forms: the "Regular Edition" and the "Deluxe Edition" which is limited to 30,000 copies worldwide. The lead-single was "I Need a Girl" featuring his bandmate G-Dragon. On July 9, 2010, Taeyang's solo album Solar hit second place on iTunes' Top R&B-Soul albums chart in the United States and first place in Canada, the first time for an Asian musician. In Solar, Taeyang put much effort into enhancing his vocal skills as well as his composing, co-writing as many as four songs ("Solar", "Where U At", "Wedding Dress", and "Take It Slow") and writing lyrics for "Take It Slow".

Taeyang's first international album, Solar International, is the first ever K-Pop music release to be sold worldwide on iTunes as both an audio and video album. The audio version (complete with a digital booklet) hit iTunes stores on August 19, 2010, while the video version (bundled with bonus, behind the scenes documentaries) arrived by September 10, 2010. The audio album combines both English and Korean hits from his past and present albums including "I'll Be There", "Connection" (feat. BIG TONE), "Wedding Dress" and "I Need a Girl (feat. G-Dragon)". On August 26, 2010, Solar's International album made it to fifth place on iTunes' Top R&B-Soul albums chart in the United States and Japan, and third place in Canada.

Solar (composition)

"Solar" (/ˈsoʊlər/ or /soʊˈlɑːr/) is a musical composition attributed to Miles Davis on the studio album Walkin' (1954), considered a modern jazz standard. The tune has been played and recorded by many musicians including his former bandmates/collaborators Lee Konitz, Bill Evans, Dave Holland, Keith Jarrett or Jack DeJohnette. A controversy exists over authorship of this composition and one current consensus holds that Davis' "Solar" is essentially an earlier song, "Sonny", written by Chuck Wayne.

The first two measures of this song adorn Miles Davis' tombstone in Woodlawn Cemetery.

Chord structure

Solar is considered a blues by most listeners, and the commonly accepted chord structure for this piece is:

SOLAR (ISS)

SOLAR is an ESA science observatory on the Columbus Laboratory, which is part of the International Space Station. SOLAR was launched with Columbus on February 2008 aboard STS-122. It was externally mounted to Columbus with the European Technology Exposure Facility (EuTEF). SOLAR has three main space science instruments: SOVIM, SOLSPEC and SOL-ACES. Together they provide detailed measurements of the Sun's spectral irradiance. The SOLAR platform and its instruments are controlled from the Belgian User Support and Operations Centre (B.USOC), located at the Belgian Institute for Space Aeronomy (BISA) in Uccle, Belgium.

Area (graph drawing)

In graph drawing, the area used by a drawing is a commonly used way of measuring its quality.

Definition

For a drawing style in which the vertices are placed on the integer lattice, the area of the drawing may be defined as the area of the smallest axis-aligned bounding box of the drawing: that is, it the product of the largest difference in x-coordinates of two vertices with the largest difference in y-coordinates. For other drawing styles, in which vertices are placed more freely, the drawing may be scaled so that the closest pair of vertices have distance one from each other, after which the area can again be defined as the area of a smallest bounding box of a drawing. Alternatively, the area can be defined as the area of the convex hull of the drawing, again after appropriate scaling.

Polynomial bounds

For straight-line drawings of planar graphs with n vertices, the optimal worst-case bound on the area of a drawing is Θ(n²). The nested triangles graph requires this much area no matter how it is embedded, and several methods are known that can draw planar graphs with at most quadratic area.Binary trees, and trees of bounded degree more generally, have drawings with linear or near-linear area, depending on the drawing style. Every outerplanar graph has a straight-line outerplanar drawing with area subquadratic in its number of vertices, If bends or crossings are allowed, then outerplanar graphs have drawings with near-linear area. However, drawing series-parallel graphs requires an area larger than n by a superpolylogarithmic factor, even if edges can be drawn as polylines.
